Abstract

Abstract:

To achieve the recycling of green garbage, evaluate quantitatively the effects of covering ecological sawdust on soil surface temperature and humidity, we measured the soil surface temperature and humidity by soil hygrometer for 1 year. The results showed that: laying ecological sawdust in winter could have good heat and moisture preservation effect, the soil moisture content without laying sawdust dropped rapidly to less than 10%, and the soil moisture content of the whole winter after laying ecological sawdust of 15-20 cm kept above 16%, and the soil temperature of the latter was 2℃ higher than that of the former; in summer, the moisture content of the sample trees with ecological sawdust of 5-10 cm was lower than that of the control group and other experimental groups without ecological sawdust, but the effects on temperature was not obvious; in winter, covering ecological sawdust had obvious heat and moisture preservation effect on soil surface, and the thicker the ecological sawdust, the more significant the effect on heat and moisture preservation; in summer, the optimal thickness of ecological sawdust was 5-10 cm, which could not only play the role of spongy body to absorb excess water, but also avoid physiological water shortage of plants due to the increase of temperature difference between canopy and root system after covering ecological sawdust. Therefore, we suggest the thickness of ecological sawdust in urban parks should be 5-10 cm.

Key words: Yuyuantan Park, cherry, organic covering, soil temperature and humidity, ecological sawdust
